That is a specious argument on multiple counts. And I speak from personal greviance as my wife and family are all Czech from the Sudetenland. Her grandfarther was rounded up by the Nazis and sent to Buchenwald for the crime of being a Czech policeman born in 1921. This is NOT that situation.

Hitler already had concentration camps in 1933 and a LOT of them by 1938. Hitler was specifically demanding the Sudetenland for "living space" for Germans. That is, his plan was to expropriate Czechs of their lives and property for Germany, as he had been doing internally in Germany with Jews, Roma, and other groups since coming to power in 1933.

Putin is a brutal dictator, no doubt. But he has been in power for 20 years, and in that time he has not created internal concentration camps for "othered" Russians and enriched "good" Russian with the property of those sent as slaves to concentration camps.

Russia has also not invaded any countries, including Ukraine, with the stated goal of making more "living space" for Russians in Russia to move to ethnically cleansed Ukraine. That has not and is not happening.

Ergo: Your argument is specious
